Ian has been appointed non-executive chairman of John Charcol.
The appointment will take place from 01 December 2011, subject to regulatory approval.
Commenting on his move, Ian Darby said: “When Towergate Financial joined the Towergate Group in 2009, I was determined to lead the business back in to profitability following a tough period of trading during an uncertain economic climate.
“Having reached this milestone, it was always my intention that I would hand over the reins of the business which is in great shape, with a strong new business pipeline and led by a first class management team.
“I look forward to the business continuing to grow under Dan’s leadership, and I will play my part in this by helping to exploit the opportunities that exist through the John Charcol channel.”
